Turned Off My Subwoofer ... And My Speakers Sound Great


I’ve had a pair of JA Pulsars (non-Graphene) for a couple of years now, and have been using them with a subwoofer. Today, I noticed that my Pulsars sounded very different. There was an expansion of soundstaging, the bass was more articulate and robust (i.e., it had more weight to it), and the highs really sparkled.

This was somewhat different from the sound to which I had become accustomed, so I looked on the panel and discovered that the sub had been turned off. Apparently, my wife had been dusting around my listening room and had accidentally hit the off switch.

I am kind of befuddled by this because I thought use of the subwoofer was supposed to achieve those sonically pleasing effects. Apparently not in my case. Have any ’Goners had this happen? I’m really happy with the "new" sound sans subwoofer, but continue to wonder why that is. I mean by all objective measures, the sub should improve the sound, not detract from it. I just don’t get it.

I know the feeling.


(I own JA Perspectives and Thiel 2.7 speakers).


I’ve never felt a burning need for a subwoofer, but like anyone I can be swayed by all the talk about how subwoofers substantially improve a sound system, even when you add them to floor standing speakers.


I bought a couple JL Audio e110 too! Also the JL Audio CR1 crossover.I initially did a bunch of experimenting, following the basic rules of adding a sub and, yes, I heard some expanded soundstage/dimensionality etc. But what I couldn’t shake is that adding the sub changed the character to my ear of the entire speaker. The tonality changed from the mids up to the highs. Even as I played with phase and volume level I could never get rid of the problem that the sub would add, but also subtract. And I’d always prefer the tonality and punch of the system without the sub.



What does this say? To me it doesn’t determine that I don’t like the trade-off with subs necessarily. It may certainly be possible to maintain the same sonic character of the speaker and only add low bass. But it DOES tell me that trying to get that balance if FRIGGIN’ HARD...and it’s no wonder you see all the subwoofer-heads talking about taking weeks even months to dial in a sub, and/or employing all sorts of trial and error with DSP to get it just right.


So, could I get it "just right" to please my picky ears?


I hold out hope. But it’s such a hassle that I haven’t bothered to try again in...I dunno...at least a year. I’m trying to get myself to set them up again, and give it a longer more rigorous try, and then decide whether to throw in the towel.


(I’ve been wanting to upgrade my Perspectives to the graphene version, but don’t have the money, so I’ve contemplated selling all my subwoofer stuff to pay for the upgrade. Which is why I want to first give them a real try first).

As I said, I have a similar concern.   Most subwoofer users will say you should crossover fairly high, 80Hz being a typical recommendation.  Then, in passing those to a subwoofer that you can place optimally and/or DSP,  you get to refine the bass in the regions most affected by the room.

But speaker designers have worked hard on producing a certain character, and the Joseph speakers have this wonderful punchy, dense, "chewy" bass quality that I'd be loathe to give up.  Not sure I'd want to replace that character with whatever comes out of a subwoofer.

I also tried a REL-like set up using line level inputs, lower crossover points etc, just augmenting, and still couldn't get around the change of character in the sound of the main speakers when doing so.
